Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
Etobicoke, ON·Google
Rated 5 out of 5
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Scarborough, ON·Google
Rated 5 out of 5
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Mississauga, ON·GuildQuality
Rated 5 out of 5
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Vaughan, ON·HomeStars
Rated 5 out of 5
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
North York, ON·Google
Rated 5 out of 5
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

FAQ
Common Questions
Most residential replacements are complete in one day. Larger homes or complex rooflines may take two. We confirm the timeline at your estimate so there are no surprises.
Every installation includes a manufacturer's material warranty (15-50 years depending on product) and a Blue Knight workmanship warranty. Both are in writing before work begins.
Yes. We photograph and document all damage in a written report formatted for insurance carriers, and work with your adjuster directly if needed.
We pull and manage all required permits. In Toronto and most GTA municipalities a permit is required for a full replacement, we handle it so you don't have to.
Homeowners Ask
What to Know About Roofing in the GTA.
The questions GTA homeowners search most, answered honestly.
$9,000-$22,000 for a typical GTA home depending on size, pitch, material, and deck condition. Flat roofs are typically $8-$14/sq ft for TPO or modified bitumen. We provide itemized written estimates.
If the leak comes from a sudden event, storm damage, falling trees, hail, it is typically covered. Leaks from gradual wear are not. We document the cause in writing to give you the strongest case with your insurer.
Across Ontario, most residential replacements land between $8,000 and $20,000. The drivers are roof size, pitch, material grade, and whether the deck underneath needs repair. Get every quote itemized in writing so you can compare like for like.
Interior waterproofing typically runs $100-$250 per linear foot; full exterior excavation runs $250-$450. A typical GTA semi is $5,000-$15,000 for a full wall. We quote from an on-site inspection, in writing, never over the phone.
